Top — Tyflow Crack

At the core of TyFlow’s destruction capabilities is the Fragment Operator. This node utilizes Voronoi decomposition to redefine the topology of a source mesh.

2.1 Voronoi Decomposition The algorithm scatters "seed points" within the volume of a mesh. It then partitions the mesh into convex hulls (cells) such that every point within a cell is closer to its generating seed than to any other. In TyFlow, this process is not merely geometric but topological: tyflow crack top

2.2 Surface Detail and Clustering To avoid the "jagged" look typical of raw Voronoi fracturing, TyFlow introduces topological modifiers such as Clustering. By noise-modifying the seed distribution, the solver creates clusters of fragments that stick together upon impact, simulating the tensile strength of materials like concrete or wood. This effectively creates a temporary topological bond that breaks only when specific kinetic thresholds are met. At the core of TyFlow’s destruction capabilities is

  • Add rigid body behavior:
  • Add forces:
  • Secondary particles:
  • Tweak timing and look:

    • In the field of Visual Effects (VFX) and architectural visualization, the simulation of destructive events—such as building collapses or shattering glass—requires a robust handling of geometric topology. The primary challenge lies in transforming a single contiguous mesh into thousands of independent rigid bodies while maintaining spatial coherence and physical plausibility. Add rigid body behavior:

    TyFlow addresses this through a dedicated "Fragment" operator and a dynamic topology management system. This paper details how the software handles the "Crack" and "Topology" aspects of simulation, specifically looking at how vertices, edges, and faces are managed during the transition from a static object to a dynamic debris field.

    TyFlow has become a go-to particle and VFX system inside 3ds Max for procedural destruction, debris, and fracture effects. One of the most useful—and visually convincing—effects you can create is a realistic crack propagation across a surface or object. This post walks through a practical, artist-friendly workflow to produce controlled, photoreal cracks using TyFlow, with tips for timing, detail, and rendering.
